Watermark

You can add watermarks to images by overlaying another image on top of your main image.

Note: The maximum accepted image size is 100,000,000 pixels. An image with this many pixels could have width and height combinations like 10,000 x 10,000 or 5,000 x 20,000, etc. There is also a file size restriction. Filestack will not convert an image that is larger than 256mb. Please contact us if you require the ability to process larger files than our current limits.

Security Example where both the image to be watermarked, and the watermark to overlay, are secured by handle specific policies. This requires the passing of two policies and two signatures. One set in the security task, and one set attached to the url of the image to be watermarked
